Name	Description
veer.config	Configuration script for VeeR-EH2

This script will generate a consistent set of defines/#defines needed for the design and testbench.
A perl hash (perl_configs.pl) and a JSON format for VeeR-iss are also generated. This set of include files :

$RV_ROOT/configs/snapshots/default
├── common_defines.vh                       # `defines for testbench or design
├── defines.h                               # #defines for C/assembly headers
├── eh2_param.vh                            # Design parameters
├── eh2_pdef.vh                             # Parameter structure
├── pd_defines.vh                           # `defines for physical design
├── perl_configs.pl                         # Perl %configs hash for scripting
├── pic_map_auto.h                          # PIC memory map based on configure size
├── link.ld                                 # Default linker control file
└── whisper.json                            # JSON file for veer-iss

While the defines fines may be modified by hand, it is recommended that this script be used to generate a consistent set.

Targets

There are 4 predefined target configurations: default, default_mt, typical_pd and high_perf that can be selected via the -target=name option to veer.config.

Target	Description
default	Default configuration. AXI4 bus interface. Single hart build.
default_mt	Dual hart build, AXI4 bus interface
typical_pd	No ICCM, AXI4 bus interface, dual hart
high_perf	Dual hart, large BTB/BHT, AXI4 interface

veer.config may be edited to add additional target configurations, or new configurations may be created via the command line -set or -unset options.
